1. AA/AMPS is copolymerization of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid
(AMPS).
2. Add distilled water dissolved with buffer and emulsifier into the reaction kettle, stir and raise
the temperature to 50 °C, while adding sodium persulfate water-soluble (5mmol/L) and mixed monomer
(acrylic acid, acrylamide, methylpropanesulfonic acid) aqueous solution dropwise to carry out
copolymerization reaction, dropwise addition time is 2H. AFTER DROPPING, CONTINUE THE HEAT
PRESERVATION REACTION FOR 0.5H.
3. By 50%-70% (mass fraction) of acrylic acid and 30%~50% of 2-acrylamido-2-methylpropylsulfonic
acid (AMPS) or 50%~95% acrylic acid and 5%~50% of 2-propylamido-2-methylpropylsulfonic acid, or
70%~30% acrylic acid and 30%~70% of 2-propylamide-2-methylpropylsulfonic acid, under the initiator
ammonium persulfate or ammonium ferrous sulfate and ammonium persulfate, The product was prepared by
reacting at 70~100 °C for 2~5h. For example, the two monomers of acrylic acid and AMPS are mixed in
a certain proportion, and then the ammonium persulfate initiator is prepared into an aqueous
solution of a certain concentration in proportion and stored separately. Control the reaction
temperature at 95 °C, add monomer and initiator dropwise, continue to keep warm for 1.5~2.0H after
dropping, and cool the product to about 40 °C.
